G08 operated on the following schedule:
- 7:00 to 10:00 UTC on 6453 kHz.
- 9:00 to 12:00 UTC on 5821 kHz (repeat of the above).
- 19:00 to 22:00 UTC on 3217 kHz.
- 21:00 to 00:00 UTC on 3820 kHz (repeat of the above).
Note that G08 adjusted its broadcast times to Daylight Saving Time. Towards the end of the Cold War, the above schedule became erratic, and few or even none of these schedules could have been heard.
